CrowdStrike to buy AI security startups Fiddler and Dreadnode for $495M
What's the deal? CrowdStrike has agreed to acquire two artificial-intelligence security startups, Fiddler AI and Dreadnode, for a combined $495 million. The company will pay roughly $400 million for Fiddler and about $95 million for Dreadnode, mostly in cash with a portion in stock subject to vesting conditions.
What do they do? Fiddler, founded in 2018 and based in Palo Alto, California, monitors and explains AI agent behavior after deployment; it will become Falcon Observe on CrowdStrike's platform. Dreadnode, founded in 2023, runs more than 100 known attack methods against models and agents to find flaws before deployment.
Why now? The deals, announced at CrowdStrike's Fal.Con Europe conference in Barcelona, target a gap that has widened as companies adopt AI agents. Such software can hold valid credentials and approved tools yet still make bad decisions, ignore instructions, or claim work it never completed — risks traditional security testing cannot catch.
What's the endgame? CrowdStrike wants to fold testing and oversight into its Falcon platform rather than leave them as separate products. "When a regulator or your board asks what an agent did, saying 'the model did it' is not an answer," said chief executive George Kurtz, describing Fiddler as "the flight recorder for every agent."
Dreadnode maps problems to standards such as the OWASP Top 10 for large language models and the NIST AI Risk Management Framework. Its chief executive, Brad Palm, said the company was built on the idea that "the people best equipped to find those failures think like attackers."
Why it matters: The acquisitions extend CrowdStrike's push to secure AI agents across their lifecycle. Fiddler adds monitoring and explainability; Dreadnode adds pre-deployment testing. The deals are expected to close in the fourth quarter of CrowdStrike's fiscal year 2027.
The signal: AI-agent security is a fast-forming category, and CrowdStrike isn't alone in chasing it — Palo Alto Networks has bought AI-focused firms including Portkey and Koi. The payoff will depend on how well CrowdStrike integrates the tools and whether customers adopt them.
